7. Lowrance HDS-9 Gen2 Touch Insight
9-Inch Touch Screen
For those who want the ultimate in fish finding technology, we have the Lowrance HDS-9 as a top rated fish finder. Not only do you get a large screen, but it’s touch activated for even more convenience. It’s so wide that you can chart two maps at once, and it’s all high-definition which allows you to create 3D models of the bottom of any lake or river in real time. Overall, this is as good as it gets.
Cartography with Maps and Navionics
The charting technology on this finder is incredible, which is why it has such a high price tag. You can find your location on the map and then scan the whole area and produce a high-quality, high-definition 3D reading. Finding fish has never been easier.
Four Channel Sonar Technology
The reason that you can develop such comprehensive scans of the bottom is that the transducer uses four separate channels. This means that you get much more than most other finders, making this the ultimate fishing accessory.

Best of all, the control panel is intuitive and enables you to work faster.
Dual Beam PLUS Sonar
While many fish finders point directly underneath your boat, higher end units like this one will sweep to the sides as well. Considering that you are casting out from the ship rather than dangling lines beneath it, side sweeping is much more valuable as it allows you to find fish wherever you are, rather than finding them, moving the boat, and then trying to catch them.
Internal GPS System
These days, if your finder doesn’t have GPS Combo, then you need to upgrade. Not only does it make it easier to pinpoint your location when you’re out on the open water, but it will help you mark hot zones so that you can return for a big haul next time.

10. Lowrance HDS-7 Gen3 Fish finder GPS Combo
Finally, we come to the HDS-7 from Lowrance. I have had limited experience with this company, but from what I know it is a fantastic maker of fish finders, and the HDS-7 is no exception. This particular model has a seven-inch touchscreen, which makes it one of the most high-tech options you can find anywhere. If you like a more ergonomic design and want something that is more user-friendly, the HDS-7 could be for you.
While this unit makes for a fantastic depth gauge, what makes it shine is the GPS options that come with it. You get a fifty-channel
GPS, which means that you get some of the best navionics possible, as well as a huge supply of pre-loaded maps to help you get started. These maps are only for North America, however, so if you go traveling outside of that region, you will have to create your charts.
The other thing that I like about this particular model is the mounting bracket. You can swivel the device on a horizontal axis, making it easier than ever to adjust the screen to your liking. Also, the housing is weather resistant, which is a nice touch.

How to Choose the Right Fish Finder
There are many factors to consider before buying a fish finder. Following these steps will provide you the information you need to find the best fish finder for the money.
- When you’re looking for a fish locator, the frequency range is important to understand which is the best one for you. There are three types of frequencies, including dual, single, and multiple frequencies. They come in 50, 83, 192, or 200 kHz.
- Higher frequencies, such as 192 or 200, are ideal for fishing in shallow water. Lower frequencies, such as 50 or 83, are perfect for deep water fishing. To find the top fish finder for the money, knowing what area you’re planning on using it in will lead to more catches. Remember that the higher the frequency, the more detail you’ll have on the screen.
- Wattage is the how the finder is powered. The more wattage you have on the fish finder, the faster the response time will be. If you have more wattage, you can see deeper into the water and find the fish. Fishing in shallow water requires less wattage for better it is to see the surrounding area.
- When you combine the frequency range and the wattage, you can get a clear picture of what it looks like under the surface. A good way to measure this is to remember that at 50 kHz with every 100 watts of power, you can read up to 400 feet deep. When you’re using 240 kHz at 100 watts of power, you’ll have readings up to 100 feet.
- Just like with TV’s and computer screens, you want a high resolution to see everything. You want a fish locator that has a screen resolution of at least 240 x 160 pixels for sight. If you find that this is too blocky, and cannot tell the differences on the screen, you can opt for a higher resolution screen.
- When you combine the resolution with the size of the screen, you’ll see more in a clearer picture. You should budget for the best screen you can get for your main fish finder. For a backup, you can settle for a smaller screen, since you won’t use it all the time.
- While the old black and white screens are becoming obsolete, they can still be practical and useful. Depending on your budget, you may need to settle for a black and white finder. They are good for those who have never had a finder before, or want one as a backup.
- Colored screens are the new standard, and they are much more reliable than their black and white counterparts. They’re easier to read in the sun and make it easy to see what’s going on around you. If you can manage it, a glowing screen will be more helpful than the black and white screen.
- The transducer is what makes the finder capable of finding fish. They emit and receive the sonar waves that let you know if there are fish and other objects nearby. When it receives the data, it sends it to the main unit and switches it to the screen. Without a transducer, your finder becomes a fancy screen that doesn’t display any data.
- While every fish locator does come with a transducer, you may want to invest in an after-market transducer. They can receive data faster, read more of the area, and work better than what comes with the box. You can start fishing right away with one, but you want to make sure you have a transducer that works for you.
- You want to consider the transducer material, cone angles, and beams for your fish finder. Also have a look fish finder review in online before purchase.
Using Your Fish Finder: Best Practices
Once you get your fish finder, you may wonder what you need to do to make sure it works correctly. This step-by-step guide will help you get setup and ready to use the finder.
Check the Manual
To understand how your fish finder works, you want to consult the manual. You can read the terms, and how to program the finder. While you may not enjoy reading the technical babble, it is a good way to familiarize yourself.
Mounting the Fish Finder
You want to put the finder in the best spot on your boat. There are a few different types of mounts you can use. You can choose from a transom, trolling, hull, or portable mount for your boat. Depending on your wants and needs, you can choose the right mount.
Setting up the Fish Finder
You want to turn the fish finder on. It will be set in automatic mode already, with the pre-program settings already on. You can switch it to a manual mode at any time to customized the finder. When you first turn it on, you can leave it in the automatic mode. You then want to drive on the water in automatic mode to get an idea of what it’s seeing.
Adjusting the Settings
The first setting you want to understand is the sensitivity. This adjusts the power of the fish finder, allowing you to see more details. When the power is lower, the quality on display is lowered. You can toy around with the fish finder to find the right setting.
Adjusting the Fish ID Setting
When the fish finder is on the automatic setting, it will identify fish automatically. It’s ideal for those who are trying to figure out their fish finder, but once you adjust to it, you can turn it off. You can see the fish arches, which will give you a better view of what's going on underneath the waves.
Using Auto Depth
If you’ve never used sonar before, you want to keep the auto depth turned on. It automatically tracks the floor of the water, making it easier to see how far down it is. When you become more experienced, you can adjust the setting. The auto depth feature can be adjusted to hide the first few feet underneath, and above the true bottom. It’s useful for setting your sights on the fish you want to catch.
The depth cursor is a line that goes across the screen. This line will let you know how far down the fish are, which makes it easy to determine where to put your bait. It will move up and down on the screen, making it easy to find the fish.
The suppressor setting is perfect for blocking out the background noise you’ll experience while you’re waypoints . This setting is normally automatic if the transducer is installed correctly, but you can adjust it for your benefit. You don’t want to keep the suppressor on all the time because it can block out the sonar.
How Does a Fish Finder Work?
Fish finders are an excellent tool that can enhance the fishing experience, and allow you to catch more fish. There are typically only two parts to a fish finder, making it easy for everyone to use. They have a screen or display that fits onto your boat and gives you the information you need to catch more fish.
They will display how far down the fish are, and how deep the water is. A fish locator uses a transducer, which takes recordings of the area near the boat using sonar. The sonar bounces off fish, rocks, coral, and other objects under the water.
When the sonar comes back to the transducer, this information is relayed to the display screen. It’s a basic computer showing raw data of what lies underneath the surface of the water. It is easy to read and understand display that will help you find where the fish are swimming.
They’re ideal for anyone who wants to get a better idea of the surrounding area under the water. Even if you use it for kayaking, it’s good to know whether you’re near any rocks or logs. You can avoid accidents and map out the water for other adventures if you’d like.
Advantage of Fish Finder GPS Combo
If you’ve used a fish finder before, then you might be wondering why it’s necessary to get one with a GPS. To be perfectly honest, if you are someone who likes to fish in your local area and either casts from the shore or the back of a small boat, then GPS capability may not be something that’s worthwhile. However, for any fisherman who likes to go searching for the best catch, having GPS installed on your finder can make a world of difference. Here are some of the best reasons to get the best GPS combo fish locator.
● Charting and Navionics: if you like to plot a course and navigate your way to prime fishing grounds, then you will need a GPS to do so properly. While most of these units come with pre-loaded maps, I find that you will want to get one that allows you to customize your charts so that you can return to the right spot every time.
● Location Saving: if you do find a perfect fishing hole, then you will want to mark it on the map, so you know where to come to next time. In this case, GPS allows you to do so with pinpoint accuracy.
● Depth Finder: because GPS models have maps and charting capabilities, that means that you get a lay of the land in a way that isn’t possible with a standard finder. This way, you can see the bottom even easier, making your depth readings much easier to decipher.
● Water Temperature: depending on where you fish, you may encounter spots where cold and warm water meet. Also, you can track your next catch based on if it’s a cold or warm water species, meaning this is a handy feature to have.
Tips and Tricks for Best Results with GPS
Even if you’ve used a fish finder before, having a Chartplotter/GPS installed means that there is a whole new level of your fishing experience. To make the most out of your added features, here are some things that you should always remember.
● Contour Lines: use these things to your advantage, as they will show you the topography of the bottom of your body of water. Many fish like to hang out in similar depths, so knowing where there are hills and valleys beneath your ship can make a huge difference in your haul.
● Buoys: when you go out into the ocean, you will see buoys to mark different depths and shipping lanes. Having a GPS means that you can see where these are without having to plot them yourself.
● Wrecks: not only do fish like to hang around shipwrecks, but you can do a little bit of exploring while you’re out on the water. Some GPS units will highlight wrecks on the map for you so you can be better prepared for them.
● Seabed: as I mentioned, some species like to hang out at certain depths. GPS tracking means that you can get a layout of the seabed when you’re out on the ocean, meaning that you can position yourself just right to get the best catch.
What is a Good Price for a Fish Finder?
There are a lot of factors that go into finding a right fish finder for the money. Depending on the type of fishing you’re doing will factor into the price tag. There are some that are under $200, while others can run up to over $1000.
You should consider where you’re fishing, what type of fish you want to catch, and what features you’ll need.If you’re on a budget, you don’t want to spend too much money on a fish finder. Some of the finders are ones that do everything you want them to do, and won’t break the bank.
If you’re looking for the ideal price for a fish finder, you may want to consider spending at least $300, or under $500, but no more than $1000. Unless you can afford some of the more expensive top rated fish finders, your range should be between $300-1000.
Overall, if you want to get the best fish finder, then our top pick has to be either the Humminbird Helix 7 or the Garmin Striker 7SV. We love the large screens and comprehensive functions that you get with both devices, as well as the rugged dependability. If you want to save money, though, the Garmin Striker 4cv will be your next best bet as it comes with high-performance results, even with a smaller screen.
